ok. From your earlier post, a couple of issues present themselves.If you are making sure all 3 phases come in; you`re NOT dealing with a 240v supplyAs regards the i/p to PLC; if all you are confirming is that a series of mcbs have all closed; the o/p from the final mcb would have changed state from *effectively* 0V to phase voltage. There`s your signal!Hope that helps. As I said earlier; a photo of the drawing would be advantageous.KME
